Labeling Experience

AI Training Data Contributor (RLHF & SFT)

TextRLHF
I contributed to data labeling projects centered on reinforcement learning from human feedback, fine-tuning large language models for accuracy, safety, and logical consistency. My responsibilities included evaluating and ranking model responses, identifying AI-generated hallucinations, and providing feedback to enhance model tone and helpfulness. I conducted detailed assessments of language quality and cultural relevance for West African contexts. • Evaluated and rated model outputs for truthfulness and reasoning. • Identified and annotated instances of hallucinations in LLMs. • Suggested improvements to tone and user helpfulness. • Provided context-aware feedback for linguistic accuracy.

Image & Video Labeling Specialist

ImageBounding Box
I contributed to computer vision projects by labeling images and videos using bounding box, semantic segmentation, and key-point annotation techniques. My work focused on accurate object detection and activity identification for AI research and development. I was responsible for ensuring data quality and consistency in large-scale vision datasets. • Created bounding boxes to annotate objects in diverse image sets. • Performed semantic segmentation to distinguish regions within images. • Conducted key-point annotations for human pose and facial recognition. • Reviewed and validated annotated datasets for quality control.

Technical Annotation & Code Labeling Specialist

I performed technical annotation and debugging of code snippets in Python and JavaScript to ensure high-quality training data for AI coding assistants. This involved detailed review, correction, and labeling of both functional and logical code elements. My role was critical for enhancing the accuracy and utility of coding LLMs. • Labeled and categorized code samples for function type and output. • Debugged code to identify logical or syntax errors. • Ensured annotation met industry standards for coding accuracy. • Worked with both educational and professional programming datasets.
